* Played for laughs in ''MetalWolfChaos'' where Jody flat-out ''guessing'' it will take the Alcatraz Cannon four minutes to recharge turns out to be accurate to the nearest hundredth of a second.

* So far one of the few practical applications for ludicrous precision that many people take for granted is GPS. A GPS receiver uses the differences in time it received radio waves from the satellites to triangulate position. The thing is, the clocks in the GPS have to be really, ''really'' accurate, on the order of being within 50ns of each other. The reason is because since you're using how long it took for the radio waves to travel (which travel at light speed), if they're off even by a microsecond, the position can be over 300 meters off. It's actually even worse than it sounds, since at that precision it has to account for both general and special relativity as well due to the satellites traveling at a much higher speed relative to you.

* The original ''WebVideo/LeeroyJenkinsVideo'': [[MemeticMutation "I'm coming up with thirty-two point three three, repeating of course, percentage of survival."]] (The [[GeniusBonus subtler]] joke is that "thirty-''three'' point three three repeating" is an [[SesquipedalianLoquaciousness overelaborate]] way of saying "1 in 3 chance," a much more believable result; so their statistics guy probably doesn't know what he's doing, much like the rest of the team.)

** The recipe for IKEA cream sauce (for their Swedish meatballs) has a similar issue: it was obviously written for metric measurements, as the recipe in America calls for 1 1/5 (!) cups of water. 1/5 cup is ''not'' a usual measurement in Amercian cooking (divisions are usually by powers of two, or by thirds), making measurement of this amount problematic. Oddly, the problem could have been avoided - 1 1/5 cups converts to ~283 mL, whereas 1 1/'''4''' cups (~296 mL) would be closer to the original intent of 300 mL.

* At one point in ''{{LightNovel/Durarara}}'' [[{{Badass}} Shizuo Heiwajima]] tells someone that there's a 0.0000000000000000000675% chance that you can kill someone with a glare before beating the shit out of him. That's roughly one in a billion trillion; if he tried it on each and every person in the world ''a trillion times'', he'd only kill about 10 of them. Must have taken a while to narrow down that probability.
